Abstract

A cable union fixed to a housing wall has a screwed connection with a seal. In the sleeve (10) is a contact (90) in the form of several bent pieces of metal for the cable screen (120). The contacts can be moved along the axis of the union. They touch the screen at one radial plane and the sleeve at another. Where they touch the screen, the ends are bent back. The other ends are held on a carrier (92) relative to which they can move, but the carrier itself is fixed to the sleeve. Also used is an insert placed inside the sleeve from one end and located by a catch. The contact carrier then sits on the insert.

Description

Die Erfindung betrifft eine Kabelverschraubung umfassend einen insbesondere mit einem Gehäuse verbindbaren Stutzen, eine in ein Inneres des Stutzens einsetzbare Dichtung sowie ein mit dem Stutzen verschraubbares Druckelement, welches auf die Dichtung im Sinne eines Anlegens derselben an ein durch die Kabelverschraubung hindurchgeführtes Kabel einwirkt.The invention relates to a cable gland comprising a connecting piece, in particular connectable to a housing, a seal which can be inserted into an interior of the connecting piece, and a pressure element which can be screwed to the connecting piece and which acts on the seal in the sense of applying the same to a cable passed through the cable screw connection.

Derartige Kabelverschraubungen sind aus dem Stand der Technik bekannt. Bei diesen dient die Dichtung dazu, das Kabel einerseits dicht zu umschließen und teilweise kraftschlüssig gegen Zug zu fixieren.Such cable glands are known from the prior art. With these, the seal is used to tightly enclose the cable on the one hand and to fix it partially non-positively against train.

Der Nachteil derartiger Kabelverschraubungen besteht darin, daß bei Verwendung von Kabeln mit einem Kabelschirm keine unmittelbare Verbindung zwischen dem Stutzen und dem Kabelschirm herstellbar ist.The disadvantage of such cable glands is that when using cables with a cable shield, no direct connection between the socket and the cable shield can be established.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Kabelverschraubung der gattungsgemäßen Art derart zu verbessern, daß eine unmittelbare elektrische Verbindung zwischen dem Kabelschirm und dem Stutzen herstellbar ist.The invention is therefore based on the object of improving a cable gland of the generic type in such a way that a direct electrical connection between the cable shield and the socket can be established.

Diese Aufgabe wird bei einer Kabelverschraubung der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, daß in dem Stutzen ein Schirmkontaktelement angeordnet ist, welches in elektrischem Kontakt mit dem Stutzen steht und mittels eines in Richtung des durchgeführten Kabels reichenden Kontaktbügels einen einen Innenleiterbereich des Kabels umschließenden Kabelschirm mit einer ersten Kontaktstelle kontaktiert.This object is achieved according to the invention in a cable gland of the type described in the introduction in that a screen contact element is arranged in the connector, which is in electrical contact with the connector and by means of a contacts a cable shield enclosing an inner conductor area of the cable with a first contact point in the direction of the lead-through cable.

Der Vorteil der erfindungsgemäßen Lösung ist darin zu sehen, daß durch das im Stutzen angeordnete Schirmkontaktelement eine unmittelbare Verbindung zwischen dem Stutzen und dem den Innenleiterbereich des Kabel umschließenden Kabelschirm herstellbar ist, wobei der Kabelschirm hierzu nicht vom Innenleiterbereich des Kabels gelöst werden muß, sondern lediglich ein den Kabelschirm umgebender Kabelaußenmantel zu entfernen ist.The advantage of the solution according to the invention can be seen in the fact that the shield contact element arranged in the socket enables a direct connection between the socket and the cable shield surrounding the inner conductor area of the cable, the cable shield not having to be detached from the inner conductor area of the cable for this purpose, but only one the outer cable sheath surrounding the cable shield must be removed.

Mit dieser Lösung ist auch bei Kabeln mit unterschiedlichem Durchmesser in besonders einfacher Weise ein elektrischer Kontakt zwischen dem Kabelschirm und dem Stutzen herstellbar, nämlich dadurch, daß das Kabelende mit teilweise um den Kabelschirm entferntem Kabelaußenmantel lediglich in die Kabelverschraubung eingeführt werden muß und durch die Dichtung fixiert werden kann, wobei der Kontaktbügel auch bei unterschiedlicher vom Durchmesser der Kabel abhängiger Position des Kabelschirms eine zuverlässige Kontaktierung ermöglicht.With this solution, even with cables of different diameters, electrical contact between the cable shield and the socket can be produced in a particularly simple manner, namely in that the cable end with the cable outer sheath partially removed from the cable shield only has to be inserted into the cable gland and fixed by the seal can be, the contact bracket allows reliable contacting even with different depending on the diameter of the cable position of the cable shield.

Der Kontaktbügel kann dabei prinzipiell die unterschiedlichsten Beweglichkeiten aufweisen. Besonders vorteilhaft ist es, wenn der Kontaktbügel in einer ungefähr parallel zu einer Längsachse der Kabelverschraubung verlaufenden Ebene bewegbar ist. Unter dieser Ebene ist die Ebene zu verstehen, in welcher sich der Kontaktbügel in allen durch die Bewegbarkeit bedingten Stellungen erstreckt.The contact bracket can in principle have a wide variety of mobility. It is particularly advantageous if the contact bracket can be moved in a plane running approximately parallel to a longitudinal axis of the cable gland. This level is to be understood as the level in which the contact bracket extends in all positions due to the mobility.

Prinzipiell wäre es ausreichend, wenn das Schirmkontaktelement einen einzigen Kontaktbügel aufweist. Besonders vorteilhaft ist es jedoch, wenn das Schirmkontaktelement mehrere Kontaktbügel aufweist, welche beispielsweise in konstanten Winkelabständen um die Längsachse der Kabelverschraubung herum angeordnet sind.In principle, it would be sufficient if the shield contact element had a single contact bracket. However, it is particularly advantageous if the shield contact element has a plurality of contact brackets which are arranged, for example, at constant angular intervals around the longitudinal axis of the cable gland.

Hinsichtlich der Herstellung einer elektrischen Verbindung zwischen dem Kontaktbügel und dem Stutzen sind die unterschiedlichsten Lösungen denkbar. So wäre es beispielsweise denkbar, daß der Kontaktbügel über ein diesen tragendes Element mit dem Stutzen elektrisch verbunden ist.A wide variety of solutions are conceivable with regard to the establishment of an electrical connection between the contact bracket and the connecting piece. For example, it would be conceivable for the contact bracket to be electrically connected to the connecting piece via an element carrying this.

Noch vorteilhafter ist es jedoch, wenn der Kontaktbügel den Stutzen mit einer zweiten Kontaktstelle unmittelbar kontaktiert, so daß eine möglichst direkte Verbindung zwischen dem Kabelschirm und dem Stutzen herstellbar ist.However, it is even more advantageous if the contact bracket contacts the socket directly with a second contact point, so that the most direct possible connection between the cable shield and the socket can be established.

Besonders vorteilhaft ist es dabei, wenn der Kontaktbügel eine knieähnliche Umbiegung aufweist, die zwischen der ersten und der zweiten Kontaktstelle liegt.It is particularly advantageous if the contact bracket has a knee-like bend that lies between the first and the second contact point.

Die knieähnliche Umbiegung läßt sich besonders vorteilhaft zur Erzeugung einer Federwirkung ausnutzen, nämlich dadurch, daß der Kontaktbügel zumindest im Bereich der knieähnlichen Umbiegung aus einem federelastischen Material hergestellt ist.The knee-like bend can be used particularly advantageously to produce a spring effect, namely in that the contact bracket is made of a spring-elastic material at least in the region of the knee-like bend.

Eine derartige knieähnliche Umbiegung dient dann in vorteilhafter Weise dazu, den Kontaktbügel sowohl im Bereich der ersten Kontaktstelle als auch im Bereich der zweiten Kontaktstelle mit ausreichender Kraft zur Herstellung eines guten elektrischen Kontakts an dem Kabelschirm bzw. dem Stutzen anzulegen.Such a knee-like bend then advantageously serves to produce the contact bracket with sufficient force both in the area of the first contact point and in the area of the second contact point good electrical contact on the cable shield or the connector.

Um ein einfaches Einschieben des Kabels mit entferntem Kabelmantel, jedoch mit noch den Innenleiterbereich umschließendem und auf diesem aufliegendem Kabelschirm bei Erzeugung eines möglichst guten elektrischen Kontakts im Bereich der ersten Kontaktstelle zu erreichen, ist vorzugsweise vorgesehen, daß der Kontaktbügel im Bereich der ersten Kontaktstelle eine kufenähnliche Umbiegung aufweist, welche ein durch den Kontaktbügel bedingtes Ablösen des Kabelschirms beim Einschieben desselben verhindert.In order to achieve a simple insertion of the cable with the cable sheath removed, but with the cable shield still surrounding the inner conductor area and resting on it while producing the best possible electrical contact in the area of the first contact point, it is preferably provided that the contact bracket in the area of the first contact point has a skid-like shape Bend, which prevents the cable shield from detaching due to the contact bracket when the same is inserted.

Um ferner einen möglichst guten elektrischen Kontakt im Bereich der zweiten Kontaktstelle zu erhalten, ist vorzugsweise vorgesehen, daß der Kontaktbügel im Bereich der zweiten Kontaktstelle eine Umbiegung aufweist, welche dazu dient, auch bei geringen Anpresskräften einen möglichst guten elektrischen Kontakt durch eine möglichst kleine Kontaktfläche zu erhalten.In order to further obtain the best possible electrical contact in the area of the second contact point, it is preferably provided that the contact bracket has a bend in the area of the second contact point, which serves to ensure the best possible electrical contact through a contact area that is as small as possible, even with low contact forces receive.

Im Zusammenhang mit der bisherigen Beschreibung der einzelnen Ausführungsbeispiele wurde lediglich darauf eingegangen, daß das Schirmkontaktelement einen oder mehrere Kontaktbügel aufweist. Besonders vorteilhaft ist es jedoch, wenn das Schirmkontaktelement ein Trägerteil aufweist, an welchem die Kontaktbügel gehalten sind.In connection with the previous description of the individual exemplary embodiments, it was only considered that the shield contact element has one or more contact brackets. However, it is particularly advantageous if the shield contact element has a carrier part on which the contact clips are held.

Vorzugsweise ist dabei das Trägerteil als in Form eines Rings gebogenes Teil ausgebildet. Besonders zweckmäßig herstellbar, insbesondere zusammen mit den Kontaktbügeln, ist das Trägerteil dann, wenn es aus einem Flachmaterialstreifen gebogen ist, welcher die Form eines offenen Rings aufweist.The carrier part is preferably designed as a part bent in the form of a ring. Can be produced particularly expediently in particular together with the contact clips, the carrier part is when it is bent from a flat material strip which has the shape of an open ring.

Ein hinsichtlich der Ausbildung des Schirmkontaktelements besonders vorteilhaftes Ausführungsbeispiel sieht vor, daß der Kontaktbügel relativ zum Trägerteil bewegbar ist und daß das Trägerteil relativ zum Stutzen fixiert angeordnet ist. Ein derartiges Schirmkontaktelement hat den Vorteil, daß einerseits über das Trägerteil die Möglichkeit besteht, die Kontaktbügel exakt im Stutzen zu positionieren, andererseits die Kontaktbügel relativ zum Trägerteil in ausreichendem Maße beweglich sind, um auch bei variierender Dicke der Kabel stets einen guten elektrischen Kontakt zwischen dem Kabelschirm und dem Stutzen herzustellen.An embodiment which is particularly advantageous with regard to the design of the shield contact element provides that the contact bracket can be moved relative to the carrier part and that the carrier part is arranged fixed relative to the socket. Such a shield contact element has the advantage that, on the one hand, there is the possibility, via the carrier part, to position the contact bracket exactly in the socket, on the other hand the contact bracket is sufficiently movable relative to the carrier part to ensure good electrical contact between the cable, even with varying thickness of the cable Manufacture cable shield and the socket.

Ein besonders vorteilhaftes Ausführungsbeispiel sieht vor, daß das Trägerteil im Abstand von einer Innenwand des Stutzens liegt und der Kontaktbügel von dem Trägerteil ausgehend zu einer und dann zur anderen Kontaktstelle verläuft, so daß der Kontaktbügel ausgehend von dem Trägerteil sowohl in Richtung der Innenwand des Stutzens als auch in Richtung des Kabelschirms ausreichend Bewegungsraum aufweist, um unterschiedliche Abmessungen durch elastische Deformation auszugleichen.A particularly advantageous embodiment provides that the carrier part is spaced from an inner wall of the connector and the contact bracket extends from the carrier member to one and then to the other contact point, so that the contact bracket starting from the carrier member both in the direction of the inner wall of the connector and also has sufficient room to move in the direction of the cable shield to compensate for different dimensions by elastic deformation.

Ein besonders einfaches Montieren des Schirmkontaktelements sieht vor, daß dieses von einem gehäuseseitigen Ende des Stutzens in diesen einsetzbar ist, da damit ein Zusammenbau der Kabelverschraubung völlig unabhängig von dem Vorhandensein oder Nichtvorhandensein des Schirmkontaktelements möglich ist. Beispielsweise ist es in diesem Fall möglich, eine Kabelverschraubung einerseits mit einer Dichtung und dem auf diese wirkenden Druckelement zu montieren und je nach Einsatzzweck entweder mit dem Schirmkontaktelement einzusetzen oder nicht.A particularly simple assembly of the shield contact element provides that it can be inserted into the end of the connecting piece in the housing, since assembly of the cable screw connection is therefore completely independent of the presence or absence of the shield contact element is possible. For example, in this case it is possible to mount a cable gland on the one hand with a seal and the pressure element acting on it and, depending on the application, either use it with the shield contact element or not.

Besonders zweckmäßig ist es dabei, wenn das Schirmkontaktelement in dem Stutzen lokal fixierbar ist, so daß das Schirmkontaktelement in einfacher Weise dazu ausgebildet werden kann, eine definierte Positionierung des Schirmkontaktelements in dem Stutzen zu erreichen.It is particularly expedient if the shield contact element can be fixed locally in the socket, so that the shield contact element can be designed in a simple manner to achieve a defined positioning of the shield contact element in the socket.

Besonders zweckmäßig ist es hierbei, wenn das Schirmkontaktelement über eine Rastverbindung am Stutzen fixierbar ist.It is particularly expedient here if the shield contact element can be fixed to the socket via a snap connection.

Das Schirmkontaktelement kann selbst direkt in dem Stutzen, beispielsweise durch lokales Fixieren des Trägerteils im Stutzen, gehalten sein.The shield contact element can itself be held directly in the socket, for example by locally fixing the support part in the socket.

Besonders vorteilhaft ist es jedoch, wenn das Schirmkontaktelement an einem in den Stutzen einführbaren Einsatzteil gehalten ist, da eine derartige Lösung den Vorteil aufweist, daß über das Einsatzteil in einfacher Weise eine Positionierung des Schirmkontaktelements im Stutzen erreichbar ist. Beispielsweise kann das Einsatzteil aus demselben Material oder aus anderem Material und in anderer Form ausgebildet sein als das Schirmkontaktelement, welches vorzugsweise aus entsprechend gebogenem metallischem Flachmaterial hergestellt ist.However, it is particularly advantageous if the shield contact element is held on an insert part that can be inserted into the socket, since such a solution has the advantage that the shield contact element can be easily positioned in the socket via the insert part. For example, the insert part can be made of the same material or of a different material and in a different shape than the shield contact element, which is preferably made from a correspondingly bent metallic flat material.

Vorzugsweise ist beispielsweise das Einsatzteil ein Kunststoffteil.For example, the insert part is preferably a plastic part.

Ein besonders einfaches Einsetzen des Einsatzteils, insbesondere unabhängig von der Dichtung, ist dann möglich, wenn das Einsatzteil von einem gehäuseseitigen Ende des Stutzens in diesen einsetzbar ist, da damit ein Zusammenbau der Kabelverschraubung völlig unabhängig von dem Vorhandensein oder Nichtvorhandensein des Einsatzteils möglich ist. Beispielsweise ist es in diesem Fall möglich, eine Kabelverschraubung einerseits mit einer Dichtung und dem auf diese wirkenden Druckelement zu montieren und je nach Einsatzzweck entweder das Einsatzteil mit dem Schirmkontaktelement einzusetzen oder nicht.A particularly simple insertion of the insert part, in particular independently of the seal, is possible if the insert part can be inserted into it from an end of the connecting piece on the housing, since assembly of the cable gland is thus completely independent of the presence or absence of the insert part. For example, in this case it is possible to mount a cable gland on the one hand with a seal and the pressure element acting on it and, depending on the application, either insert the insert with the shield contact element or not.

Besonders zweckmäßig ist es dabei, wenn das Schirmkontaktelement mittels des Einsatzteils in dem Stutzen lokal fixierbar ist, so daß das Einsatzteil in einfacher Weise dazu ausgebildet werden kann, eine definierte Positionierung des Schirmkontaktelements in dem Stutzen zu erreichen.It is particularly expedient if the shield contact element can be fixed locally in the socket by means of the insert part, so that the insert part can be designed in a simple manner to achieve a defined positioning of the shield contact element in the socket.

Besonders zweckmäßig ist es hierbei, wenn das Einsatzteil über eine Rastverbindung am Stutzen fixierbar ist.It is particularly expedient here if the insert part can be fixed to the connection piece via a snap-in connection.

Das Schirmkontaktelement läßt sich besonders günstig dadurch positionieren, daß dieses durch das an dem Einsatzteil sitzende Trägerteil am Einsatzteil gehalten ist.The shield contact element can be positioned particularly favorably in that it is held on the insert part by the carrier part seated on the insert part.

Vorzugsweise ist dabei vorgesehen, daß das Trägerteil an dem Einsatzteil kraftschlüssig fixiert ist.It is preferably provided that the carrier part is non-positively fixed to the insert part.

Die erfindungsgemäße Kabelverschraubung kann hinsichtlich der Ausbildung der Dichtung in unterschiedlichster Art und Weise ausgeführt sein. So ist es beispielsweise denkbar, als Druckelement eine Druckschraube und als Dichtung eine durch Pressung in axialer Richtung deformierbare und an einem einen Durchlaß durchsetzenden Kabel zur Anlage bringbare Dichtung einzusetzen.The cable gland according to the invention can be designed in a wide variety of ways with regard to the design of the seal. For example, it is conceivable to use a pressure screw as the pressure element and a seal that can be deformed by pressing in the axial direction and can be brought into contact with a cable that passes through a passage as a seal.

Alternativ dazu ist bei einem vorteilhaften Ausführungsbeispiel vorgesehen, daß in einem Inneren des Stutzens ein Dichtungsträger mit einem an diesem gehaltenen Lamellenkorb eingesetzt ist und daß in dem Lamellenkorb eine Dichtung liegt.As an alternative to this, in an advantageous exemplary embodiment it is provided that a seal carrier with a plate basket held thereon is inserted in an interior of the connecting piece and that a seal lies in the plate basket.

In diesem Fall ist das Druckelement vorzugsweise als den Lamellenkorb übergreifende Hutmutter ausgebildet, welche auf den Lamellenkorb so einwirkt, daß dieser die Dichtung in Richtung einer Längsachse der Kabelverschraubung verpreßt, um die Dichtung an einem Kabelaußenmantel des hindurchgeführten Kabels zur Anlage zu bringen.In this case, the pressure element is preferably designed as a cap nut overlapping the lamellar basket, which acts on the lamellar basket in such a way that it presses the seal in the direction of a longitudinal axis of the cable gland in order to bring the seal into contact with an outer jacket of the cable which is passed through.

Ein in Fig. 1 und 2 dargestelltes Ausführungsbeispiel einer erfindungsgemäßen Kabelverschraubung umfaßt einen als Ganzes mit 10 bezeichneten elektrisch leitend ausgebildeten Stutzen, welcher einen zylindrischen Ansatz 12 mit einem Außengewinde 14 aufweist, mit welchem der Stutzen 10 in eine Wand 16 beispielsweise eines Gehäuses einschraubbar ist.An embodiment shown in FIGS. 1 and 2 of a cable gland according to the invention comprises an electrically conductive socket, designated as a whole by 10, which has a cylindrical projection 12 with an external thread 14, with which the socket 10 can be screwed into a wall 16, for example of a housing.

Der Stutzen umfaßt ferner einen Schlüsselflächenabschnitt 18, welcher mit Schlüsselflächen 20 versehen ist und auf einer einem gehäuseseitigen Ende 22 des zylindrischen Ansatzes 12 gegenüberliegenden Seite unmittelbar an den zylindrischen Ansatz 12 anschließt.The socket further comprises a key surface section 18, which is provided with key surfaces 20 and directly adjoins the cylindrical extension 12 on a side opposite a housing-side end 22 of the cylindrical extension 12.

Auf einer dem zylindrischen Ansatz 12 gegenüberliegenden Seite des Schlüsselflächenabschnitts 18 des Stutzens 10 ist ein Zylinderabschnitt 24 vorgesehen, welcher ein Außengewinde 26 trägt. Auf das Außengewinde 26 ist eine als Ganzes mit 28 bezeichnete Hutmutter 28 mit ihrem Innengewinde 30 aufschraubbar.On a side of the key surface section 18 of the socket 10 opposite the cylindrical extension 12, a cylinder section 24 is provided, which carries an external thread 26. A cap nut 28, designated as a whole by 28, can be screwed onto the external thread 26 with its internal thread 30.

Der Zylinderabschnitt 24 dient zur Aufnahme eines als Ganzes mit 32 bezeichneten Dichtungsträgers welcher mit einem Halteansatz 34 in den Zylinderabschnitt 24 eingreift und an einer inneren Zylinderfläche 36 desselben geführt ist. Ferner stützt sich der Dichtungsträger 32 mit einer Flanschfläche 38 auf einer dem Schlüsselflächenabschnitt 18 abgewandten Stirnseite 40 der Zylinderabschnitts 24 ab und ist dadurch in Richtung einer Längsachse 42 der erfindungsgemäßen Kabelverschraubung gegen eine Verschiebung in Richtung des Schlüsselflächenabschnitts 18 fixiert.The cylinder section 24 serves to receive a seal carrier, designated as a whole by 32, which engages with a holding projection 34 in the cylinder section 24 and is guided on an inner cylinder surface 36 thereof. Furthermore, the seal carrier 32 is supported with a flange surface 38 on an end face 40 of the cylinder section 24 facing away from the key surface section 18 and is therefore in Fixed in the direction of a longitudinal axis 42 of the cable gland according to the invention against displacement in the direction of the flats section 18.

Der Dichtungsträger 32 umfaßt ferner einen Lamellenkorb 44, der seinerseits eine Dichtung 46 umschließt, wobei die Dichtung 46 ferner durch einen inneren Ansatz 48 gegen eine Verschiebung in Richtung der Längsachse 42 zum Schlüsselflächenabschnitt 18 hin fixierbar ist.The seal carrier 32 further comprises a lamellar basket 44, which in turn encloses a seal 46, the seal 46 being further fixable by an inner shoulder 48 against displacement in the direction of the longitudinal axis 42 towards the key surface section 18.

Der Lamellenkorb 44 ist seinerseits durch eine Schrägfläche 50 der Hutmutter 28 beaufschlagbar, welche bei zunehmendem Aufschrauben der Hutmutter 28 auf das Außengewinde 26 die Lamellen des Lamellenkorbs 44 zunehmend in Richtung der Längsachse 42 deformiert und damit die in dem Lamellenkorb 44 aufgenommene Dichtung 46 ebenfalls soweit in Richtung der Längsachse 42 bewegt, daß ein innerer Durchlaß 52 an einer Kabelaußenmantelfläche 54 eines Kabels 56 dichtend mit Pressung anlegbar ist.The lamellar basket 44 can in turn be acted upon by an inclined surface 50 of the cap nut 28, which increasingly deforms the lamellas of the lamellar basket 44 in the direction of the longitudinal axis 42 as the cap nut 28 is screwed onto the external thread 26 and thus also the seal 46 received in the lamellar basket 44 as far as in Moves in the direction of the longitudinal axis 42 so that an inner passage 52 can be sealingly pressed against an outer surface 54 of a cable 56.

Das Kabel 56 verläuft dabei durch eine zur Längsachse 42 koaxiale Öffnung 58 der Hutmutter 28, dann durch den Durchlaß 52 der Dichtung 46 hindurch und passiert dann einen inneren Durchbruch 60 des Dichtungsträgers 32. Im Anschluß an den Dichtungsträger 32 erstreckt sich das Kabel 56 durch einen Innenraum 62 des Stutzens 10, welcher sich ausgehend vom Zylinderabschnitt 24 durch den Schlüsselflächenabschnitt 18 und den zylindrischen Ansatz 12 bis zu einer gehäuseseitigen Öffnung 64 des Stutzens ausdehnt. Von der gehäuseseitigen Öffnung 64 ausgehend erstreckt sich in dem Innenraum 62 ein als Ganzes mit 66 bezeichnetes Einsatzteil, welches einen Ringkörper 68 mit einer radial außenliegenden zylindrischen Fläche 70 und einen über die zylindrische Fläche 70 radial nach außen reichenden Flansch 72 aufweist, welcher an einer Stirnfläche 74 des gehäuseseitigen Endes 22 des Stutzens 10 anliegt.The cable 56 runs through an opening 58 of the cap nut 28 which is coaxial with the longitudinal axis 42, then through the passage 52 of the seal 46 and then passes through an inner opening 60 of the seal carrier 32. Following the seal carrier 32, the cable 56 extends through a Interior 62 of the connector 10, which extends from the cylinder section 24 through the key surface section 18 and the cylindrical extension 12 to an opening 64 on the housing side of the connector. Starting from the housing-side opening 64 extends into the interior 62 as a whole with 66 insert, which has an annular body 68 with a radially outer cylindrical surface 70 and a flange 72 which extends radially outward through the cylindrical surface 70 and which abuts an end face 74 of the housing-side end 22 of the connecting piece 10.

Das Einsatzteil 66 weist ferner von dem Innenkörper 68 ausgehende und sich in Richtung der Längsachse 42 erstreckende Finger 76 auf, welche mit einer bezüglich der Längsachse 42 radial nach außen stehenden Rastnase 78 in eine vorzugsweise im Bereich des Schlüsselflächenabschnitts 18 liegende und sich ausgehend von der inneren Zylinderfläche 36 radial nach außen erstreckende Nut 80 im Stutzen 10 eingreift.The insert part 66 also has fingers 76 which extend from the inner body 68 and extend in the direction of the longitudinal axis 42 and which, with a locking lug 78 which is radially outward with respect to the longitudinal axis 42, into a finger which is preferably located in the region of the key surface section 18 and which starts from the inner one Cylinder surface 36 engages radially outwardly extending groove 80 in the nozzle 10.

Das Einsatzteil 66 ist somit vom gehäuseseitigen Ende 22 her in den Innenraum 62 des Stutzens 10 einschiebbar, wobei die Finger 76 elastisch in Richtung der Längsachse 42 verbiegbar sind, so daß die Nasen 78 derselben auf der inneren zylindrischen Fläche 36 von der Öffnung 64 bis zur Nut 80 entlanggleiten und dann in die Nut 80 eingreifen und somit eine Rastverbindung mit dieser bilden, während gleichzeitig der Flansch 72 am gehäuseseitigen Ende 22 des Stutzens 10 anliegt.The insert part 66 can thus be inserted from the housing-side end 22 into the interior 62 of the socket 10, the fingers 76 being elastically bendable in the direction of the longitudinal axis 42, so that the lugs 78 thereof on the inner cylindrical surface 36 from the opening 64 to Slide along groove 80 and then engage in groove 80 and thus form a snap-in connection with it, while at the same time flange 72 abuts housing-side end 22 of connecting piece 10.

Das Einsatzteil 66 trägt ein als Ganzes mit 90 bezeichnetes Schirmkontaktelement, welches mit einem in Form eines offenen Rings ausgebildeten Trägerteil 92 auf der zylindrischen Fläche 70 des Ringkörpers 68 aufliegt, wobei das Trägerteil 92 ein zu einem offenen Ring gebogener Flachmaterialstreifen ist. Zur Fixierung des Trägerteils 92 auf der Zylinderfläche 70 wird das Trägerteil 92 von von dem Flansch 72 vorspringenden Vorsprüngen 94 gehalten, welche das Trägerteil 92 auf einer der zylindrischen Fläche 70 abgewandten Außenseite 96 übergreifen, so daß das Trägerteil in einem zwischen den Vorsprüngen 94 und der zylindrischen Fläche 70 gebildeten Schlitz fixiert ist.The insert part 66 carries a shield contact element, designated as a whole by 90, which rests with a carrier part 92 in the form of an open ring on the cylindrical surface 70 of the ring body 68, the carrier part 92 being a flat material strip bent into an open ring is. To fix the carrier part 92 on the cylindrical surface 70, the carrier part 92 is held by projections 94 projecting from the flange 72, which overlap the carrier part 92 on an outer side 96 facing away from the cylindrical surface 70, so that the carrier part is in a between the projections 94 and the cylindrical surface 70 formed slot is fixed.

Von dem Trägerteil 92 erstrecken sich zwischen den Fingern 76 liegende Kontaktbügel 100, welche ein dem Trägerteil 92 abgewandtes Ende 102 mit einer V-förmigen Umbiegung 104 aufweisen, welche an einem ersten Bügelarm 106 angeordnet ist. Der erste Bügelarm 106 und ein zweiter Bügelarm 108 sind über eine knieähnliche Umbiegung 110 miteinander verbunden. Der zweite Bügelarm 108 schließt sich an eine umgekehrt V-förmige Umbiegung 112 an und diese liegt zwischen einem dritten, vom Trägerteil 92 bezüglich der Längsachse 42 radial nach außen wegführenden Bügelarm 114 und dem zweiten Bügelarm 108.From the support part 92 extend between the fingers 76 lying contact bracket 100, which have an end 102 facing away from the support part 92 with a V-shaped bend 104, which is arranged on a first bracket arm 106. The first bracket arm 106 and a second bracket arm 108 are connected to one another via a knee-like bend 110. The second bracket arm 108 adjoins an inverted V-shaped bend 112 and this lies between a third bracket arm 114 leading radially outward from the carrier part 92 with respect to the longitudinal axis 42 and the second bracket arm 108.

Jeder Kontaktbügel 100 dient zur Herstellung eines elektrischen Kontakts zwischen einem Kabelschirm 120, welcher auf einem Innenleiterbereich 122 des Kabels 56 und diesen umschließend anliegt. Unter dem Innenleiterbereich 122 werden alle von dem Kabelschirm 120 umschlossenen Unterbestandteile verstanden. Hierzu berührt der Kontaktbügel 100 mit der V-förmigen Umbiegung 104 den Kabelschirm 120 mit einer ersten Kontaktstelle 124. Ferner erstreckt sich jeder Kontaktbügel 100 vorzugsweise in einer durch die Längsachse 42 hindurch verlaufenden Ebene und ist in der Ebene liegend federnd bewegbar, wobei die Bügelarme 106, 108 und 114 in der Ebene liegend verbleiben.Each contact clip 100 serves to establish an electrical contact between a cable shield 120, which rests on an inner conductor region 122 of the cable 56 and surrounds it. The inner conductor area 122 is understood to mean all sub-components enclosed by the cable shield 120. For this purpose, the contact bracket 100 with the V-shaped bend 104 touches the cable shield 120 with a first contact point 124. Furthermore, each contact bracket 100 preferably extends in a plane running through the longitudinal axis 42 and is resiliently movable in the plane, the bracket arms 106 , 108 and 114 remain lying in the plane.

Ferner berührt der Kontaktbügel 100 den Stutzen 10 im Bereich seiner inneren zylindrischen Fläche 36 mittels der umgekehrt V-förmigen Umbiegung 112 unter Bildung einer zweiten Kontaktstelle 126. Aufgrund der Form des Kontaktbügels 100 liegt zwischen der ersten Kontaktstelle 124 und der zweiten Kontaktstelle 126 die knieähnliche Umbiegung 110 mit dem von dieser wegführenden ersten Bügelarm 106 und dem zweiten Bügelarm 108, welche bei elastischem Material des Kontaktbügels eine Federwirkung entfaltet, die einerseits die Umbiegung 104 gegen den Kabelschirm 120 und andererseits die Umbiegung 112 gegen die innere zylindrische Fläche 36 des Stutzens 10 drückt und somit auch den elektrischen Kontakt im Bereich der ersten Kontaktstelle 124 und der zweiten Kontaktstelle 126 aufrecht erhält.Furthermore, the contact bracket 100 touches the socket 10 in the region of its inner cylindrical surface 36 by means of the reverse V-shaped bend 112 to form a second contact point 126. Because of the shape of the contact bracket 100, the knee-like bend lies between the first contact point 124 and the second contact point 126 110 with the first bracket arm 106 and the second bracket arm 108 leading away therefrom, which, in the case of elastic material of the contact bracket, has a spring action which, on the one hand, presses the bend 104 against the cable shield 120 and, on the other hand, the bend 112 against the inner cylindrical surface 36 of the connector 10 and thus also maintains electrical contact in the area of the first contact point 124 and the second contact point 126.

Dadurch, daß der dritte Bügelarm 114 von dem Trägerteil 92 radial nach außen bis zur umgekehrt V-förmigen Umbiegung 112 verläuft, bildet sich auch zwischen dem Trägerteil 92 und der Umbiegung 112 ein Hebelarm, welcher eine federnde Bewegung der Umbiegung 112 in Richtung der inneren zylindrischen Fläche 36 des Stutzens 10 zuläßt, so daß durch die Ausbildung des Kontaktbügels 100 aus federelastischem Material sowohl ein Kontakt im Bereich der ersten Kontaktstelle 124 als auch ein Kontakt im Bereich der zweiten Kontaktstelle 126 stets aufrechterhalten wird.Characterized in that the third bracket arm 114 extends radially outward from the carrier part 92 to the reversely V-shaped bend 112, a lever arm is also formed between the carrier part 92 and the bend 112, which lever arm makes a resilient movement in the direction of the inner cylindrical Surface 36 of the socket 10 allows, so that the contact bracket 100 made of resilient material, both a contact in the area of the first contact point 124 and a contact in the area of the second contact point 126 is always maintained.

Bei der erfindungsgemäßen Kabelverschraubung ist es somit lediglich erforderlich, einen Kabelaußenmantel 130 soweit zu entfernen, daß der den Innenleiterbereich 122 umschließende Kabelschirm 120 freigelegt ist, jedoch noch nach wie vor den Innenleiterbereich 122 eng umschließt. Wird ein derart von dem Kabelaußenmantel 130 teilweise befreites Kabel 56 in die erfindungsgemäße Kabelverschraubung eingeschoben und zwar so weit, daß der freigelegte Kabelschirm 120 im Bereich des Innenraums 62 liegt, so wird automatisch mittels der mehreren Kontaktbügel 100 ein elektrischer Kontakt zwischen dem Kabelschirm 120 und dem Stutzen 10 hergestellt. Vorzugsweise wird dabei das Kabel 56 so weit eingeschoben, daß der mit dem Kabelaußenmantel 130 noch versehene Bereich im Durchlaß 52 der Dichtung 46 liegt, so daß durch Anziehen der Hutmutter 28 die Dichtung 46 zur Anlage an der Kabelaußenmantelfläche 54 bringbar und somit das Kabel 56 in der Kabelverschraubung einerseits abgedichtet und andererseits zumindest kraftschlüssig zugentlastet fixierbar ist, während gleichzeitig ein elektrischer Kontakt zwischen dem Kabelschirm 120 und dem Stutzen 10 über die Kontaktbügel 100 herstellbar ist.In the case of the cable gland according to the invention, it is therefore only necessary to remove an outer cable sheath 130 to such an extent that the cable shield 120 surrounding the inner conductor region 122 is exposed, but still tightly surrounds the inner conductor region 122. Will such a the cable outer sheath 130 partially freed cable 56 inserted into the cable gland according to the invention to such an extent that the exposed cable shield 120 lies in the area of the interior 62, an electrical contact between the cable shield 120 and the socket 10 is automatically established by means of the plurality of contact brackets 100. Preferably, the cable 56 is inserted so far that the area still provided with the cable outer jacket 130 lies in the passage 52 of the seal 46, so that the seal 46 can be brought into contact with the cable outer jacket surface 54 by tightening the cap nut 28 and thus the cable 56 in the cable gland is sealed on the one hand and on the other hand can be fixed at least non-positively with strain relief, while at the same time an electrical contact between the cable shield 120 and the socket 10 can be established via the contact bracket 100.
